Window & door mastic in Baldslow, East Sussex
Our applicators work in Baldslow on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- Mastic that has split away from the wall
- Black, perished sealant on frames
- Gaps left after new windows were fitted
How we handle window mastic in Baldslow
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you have leaking joints at the ends of sills and black, perished sealant on frames, we can put it right, whatever the surface.
Around Baldslow, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
When to call us in Baldslow
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
Keep an eye out for any of the following:
- Gaps where the sill meets the wall
- Mastic that is falling out in pieces
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
If you look after a building such as Ark Helenswood Academy, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Whether you can choose the colour
- Is VAT in the price?
- What insurance they hold
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. In a small place like Baldslow, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky

Advice
Different surfaces, different methods
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that, where a rigid one would crack.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
Common questions in Baldslow
Does the coastal weather in Baldslow affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you cover smaller places like Baldslow?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Are you fully insured?
Yes. Full insurance covers our work.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Frames and glazing around Baldslow
Baldslow is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Durhamford Manor (about 3.8 miles north-west) nearby, there’s older building stock in the area around Baldslow as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Ore station? Then renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Church of St John the Evangelist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the quote in Baldslow
There’s no set price list, because no two jobs are the same. The quote depends on:
- The size of the job
- Which sealant suits the joint
- How many areas need sealing
- Working hours on commercial sites
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Whether it has been sealed before
- The type of property
- Photos by email, if that is easy
- How we’d reach the joints
Every job is quoted individually, so start by telling us what you need. Simply call 0345 464 0079 or email us and describe the job and send pictures if you have them.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. Older cottages and farmhouses around Baldslow can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep paint and stain on wooden frames in good order
- Paint up to the joint, not over it
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
